Abstract
The conference room amplified sound bases on the functional requirements of the hal to determine the indicators of sound pressure level, and then design the amplified sound system, referring to the problems of construction sound analy-sis and electro-acoustic analysis. As the conference room, peo-ple first analysis of the parameters of architectural acoustics to obtain the acoustic characteristics. Then from the meeting roo-m features architectural acoustics and the request parameters of conference room to derive the requirements of conference room acoustic system.关键词
